Crank case ventilation and negative pressure

Post by Zamani »

I think there's merit in creating negative crankcase pressure. But maybe it has more to do with seal longevity as opposed to "free horsepower". I don't like the fact that hot crankcase air gets into the intake. For a road car, emissions forces you to do this, but for an off-road car, I question the need for routing hot oily air back into the intake.
